Looks like a female Castiarina imitator to me.
I think the species groups of Barker can be quite fluid and sometimes fairly subjective (Shelley would be happy to confirm this I’m sure!) so I would discount that until you get a chance to compare this specimen with other Castiarina imitator at ANIC.

The elytra of this beetle have smooth intervals (spaces between the rows of punctures). This eliminates Castiarina imitator - a member of Barker's 'bella species-group' in his 2006 Castiarina book - as one of the defining chararacters of that group is 'dorsal surface with close heavy punctures', giving that surface a matt appearance.

Understanding which species occur within a bioregion and eliminating those which do not match with habitat and morphology is a good means at arriving to species level. X. glauca angustifolia and X. resinosa are the only other candidates in this area, neither of which resemble this specimen.

Xanthorrhoea concava

Hi Mark. Any luck when checking your collection, or do we still regard it as an Undescribed species?

Castiarina sp. Undescribed species 1

Think Amorbus due to thickness of back legs present in male A. Obscuricornius

Amorbus obscuricornis
